Futureshop/bestbuy may have some decent computer items available, but it's usually online sales only. The items page tells you availability, and those fans are online only.

Ive got an h100 myself and I've noticed a pulsating hum that goes away when I disconnect the fans. WTFFFF?! I want to replace them but I've read I'll need to control them separately as the pump unit will only control the oem ones. Fact/fiction?
